Web Services is nothing but Java itself :). I realized that after I deployed Apache Axis on my web server. But anyway, it’s so fascinating, you can communicate in any manner, in any ways, to invoke something just by giving simple messages into the service.
WSDL also make everything become easy, it’s pure in XML-based services. It just give you description on how to access the web service, and what operations to do. And the rest, give it to you. Create your own interface, your own world, and ask the Web Service to do the rest, and just wait for the response.
I start to like this thing. Start digging now ! 😀
